Answer:
Step-by-step explanation:
If your mind works better in degrees than it does radians, as does mine, it will be beneficial to us to see what degree measure this angle is. Convert it to degrees using the fact that 180° = π:
degrees
Now that we know that, we can plot that angle in a coordinate plane. The terminal side of the angle lands in quadrant 2. To find the reference angle, we subtract 120 from 180 and get that the reference angle is 60 degrees, which is the same as π/3.
I kno that 2 negative together u add them so (-7)
Answer:
4 and -3 i think
Step-by-step explanation:
the dot is on 4 and -3
The answer is 4. 76 divided by 19 is 4. 19 is the only number that can go into 19. hope this helps :)
Answer:
a) 0.3889
b) 0.5
c) 0.8333
d) The mean is 250 and the standard deviation is 51.96.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability of finding a value of X higher than x is:
The probability of finding a value of X between c and d is:
The mean and the standard deviation are, respectively:
A random variable follows the continuous uniform distribution between 160 and 340.
This means that
a)
b)
c)
d)
The mean is 250 and the standard deviation is 51.96.
